| Abstract: | The criterion is based on the maximization of the stand present net value over an infinite series of rotations. The optimal control model of a timber harvest for the even-aged stand is established by using the variational solution. An example of larch plantation with the data (260 plots and 62 sample trees) from that of Northeastern range is used to illustrate how to determine the parameters and apply the model. The optimal thinning schedule and rotation for larch plantation are determined. |
